Description
Technical field
The present invention relates on recording medium the image recording of recording picture.
Background technology
In the ink-jet printer of one of image recording, have a kind of by comparing, be configured in the feed roller of position of the upstream side of printing paper throughput direction with the printable area of printhead subtend, can supply with the mechanism (for example, patent documentation 1) of printing paper to printable area.Here, feed roller comprises driving wheel and pressure roller, and their width all is slightly larger than the width of printable area.
In addition, as relevant printer, following product is widely known by the people: by along the printhead ejection ink perpendicular to the direction back and forth movement of printing paper throughput direction, print image on the printing paper that the coiling portion from the long printing paper of reeling is uncoiled, carries.This printer, the continuous back and forth movement of print head prints the printing paper of halted state, when printhead moves to a certain end at least in the end positions of back and forth movement, printing paper just with fixed paper feeding amount be that unit is by intermittent delivery.And, in print procedure, if after the printing paper swing (comprising sideslip), the image quality that prints will significantly reduce, so the time again and again with above-mentioned paper feeding amount intermittent delivery printing paper; Also need to adjust feed roller, so that printing paper is swung hardly.
[patent documentation 1]
The spy opens 2001-277543 communique (Fig. 1)
Yet in relevant printer, sometimes in order to improve its disposal ability, in printable area, two printing papers narrower to width configuration arranged side by side, that carried almost print simultaneously.Therefore, two printing papers of configuration side by side after two other uncoilings of winding part all by above-mentioned feed roller clamping, carry with speed much at one.In addition, two printing papers carry out balanced configuration, conveying with feed roller width center usually.
Therefore, in two printing papers, when only giving one to print, the printing paper that does not print just can be by the feed roller clamping, and the printing paper that only prints is by feed roller clamping, conveying.At this moment, feed roller has only clamping on one side, fed printing sheet concerning its width center.So, be not configured in when being symmetrical on the feed roller width center at printing paper, when fed printing sheet, can occur swing mostly, thereby reduce print quality.
Therefore,, on relevant printer, dispose feed roller respectively in order to address this problem, corresponding with two printing papers of configuration arranged side by side, so that can distinguish independent fed printing sheet.Like this, even when only carrying printing paper in two printing papers of configuration side by side, because printing paper is the center balanced configuration according to the feed roller width corresponding with it, so printing paper is swung hardly.In addition, as the motor of each driving wheel that drives feed roller, employing can obtain the servomotor of higher paper feeding precision mostly.
And in the printer that can distinguish 2 printing papers of independent conveying, when printing on the wide cut printing paper with width of crossing over 2 printing paper transport paths, the wide cut printing paper conveying by 2 feed roller clampings.So when utilizing 2 feed rollers to carry the wide cut printing paper, preferably 2 feed rollers are controlled to and act in agreement.
; act in agreement even 2 feed rollers are controlled to; but because of the precision difference of 2 feed rollers, promptly constitute the driving rolls of feed roller and mechanism of paper holding individual difference, drive the individual difference etc. of the motor of driving rolls; still can make the carrying capacity (paper feeding amount or transporting velocity) of 2 feed rollers different; carry laod unbalance, and cause the swing of wide cut printing paper.When especially using above-mentioned servomotor, be subjected to the influence of wide cut printing paper load easily, the wide cut printing paper forms uneven active force because of the difference of left and right sides transporting velocity, thereby swing easily.Like this, when the wide cut printing paper was swung, the ink drop point site to occur improper etc. because of meeting, thereby the image quality that is printed on the wide cut printing paper is descended.In addition, when not staying the printing at edge, the end of broad printing paper width tends to exceed the ink receiving portion of not staying edge printing to use, often will be intended to support the lettering platen of the printing paper that prints by the ink of printhead ejection and make dirty.

Travelling carriage 12 in moving way, be installed in the printing paper sensor 38 on the travelling carriage 12, as shown in Figure 8, when relative with the right end position of wide cut printing paper 2 ', printing paper sensor 38 detects the right end position (step S104) of wide cut printing paper 2 '.Therefore, at this moment, controller 20 can be known the position of the travelling carriage 12 when printing paper sensor 38 detects the right end position of wide cut printing paper 2 ' when travelling carriage 12 back and forth movements.Then, travelling carriage continues toward moving, as shown in Figure 9, the wide cut printing paper 2 ' of halted state is printed (step S105).
Then, travelling carriage 12 at it in moving, after the printing of wide cut printing paper 2 ' finished, as shown in figure 10, move to the position of turning around (position of turning around of an opposite side) of back and forth movement with position of rest after, at this constantly, travelling carriage 12 temporarily stops to move.At this moment, wide cut printing paper 2 ' is carried fixed paper feeding amount (step S106).In addition, when travelling carriage 12 is in the end positions of back and forth movement, printing paper 2 ' decide paper feeding amount, can suitably set according to the resolution ratio of the spacing between the nozzle of printhead 11, number of nozzle and print image etc.Then, wide cut printing paper 2 ' decide paper feeding amount conveying finish after, as shown in figure 11, travelling carriage 12 is on one side to returning with direction opposite when moving, on one side the wide cut printing paper 2 ' of halted state is printed (step S107).
Return in the process at travelling carriage 12, after upward printing finishes toward wide cut printing paper 2 ', travelling carriage 12 is in the way of returning, be installed in printing paper sensor 38 on the travelling carriage 12 when relative with the right end position of wide cut printing paper 2 ' once more, as shown in figure 12, printing paper sensor 38 detects the right end position (step S108) of wide cut printing paper 2 ' once more.Therefore, at this moment, controller 20 can return in the process at travelling carriage 12, knows the position of travelling carriage 12 when printing paper sensor 38 is relative with the right end position of wide cut printing paper 2 '.
Like this, controller 20 can not only be according to the right end position at the right end position of returning detected wide cut printing paper 2 ' in the process of travelling carriage 12 and correct printing paper transport path, calculate oscillating quantity when moving (dislocation of the right end position of the right end position of wide cut printing paper 2 ' and correct printing paper transport path), can also calculate the oscillating quantity (step S109) when returning according to right end position at the right end position of returning detected wide cut printing paper 2 ' in the process of travelling carriage 12 and correct printing paper transport path.
Then, controller 20 according to above-mentioned when moving oscillating quantity and the oscillating quantity when returning, detect the deflection of wide cut printing paper 2 ' and throughput direction, judge whether deflection (step S110) of wide cut printing paper 2 '.In the present embodiment, in the oscillating quantity when moving and the oscillating quantity when returning be when zero, conclude not deflection of wide cut printing paper 2 ', otherwise just conclude wide cut printing paper 2 ' deflection.
Now, consult Figure 14, controller 20 according to the oscillating quantity when moving and the oscillating quantity when returning, is made a presentation an example of the detection method of the angle excursion of wide cut printing paper 2 ' and throughput direction.Figure 14 is the figure of drawing for an example of the detection method of the angle excursion of introducing wide cut printing paper and throughput direction, is near the situation the right-hand member of Fig. 7 and wide cut printing paper 2 ' shown in Figure 10 to be overlapped to draw form.Because when being in the end positions of travelling carriage 12 back and forth movements, carry wide cut printing paper 2 ' fixed paper feeding amount smaller, so wide cut printing paper 2 ' is transported to the state (illustrating with solid line) of Figure 10 by the state (being shown in broken lines) of Fig. 7 in Figure 14 in Figure 14 when, with respect to the deflection of wide cut printing paper 2 ' throughput direction, be not similar to sharply variation.
Here, for example, for printable zone, under the situation of the deflected condition conveying that wide cut printing paper 2 ' has been alarmmed with left side shoulder, if the oscillating quantity during past moving is apart from x (wherein x＞0), oscillating quantity when returning be distance y (y＞x) wherein, wide cut printing paper 2 ' intermittent delivery to decide paper feeding amount be apart from a.Therefore, at this moment, the deflection of wide cut printing paper 2 ' and throughput direction can be used as the angle θ that satisfies following formula 1 and calculates.
Tan θ=(y-x)/a (formula 1)
And, as previously mentioned, when concluding wide cut printing paper 2 ' deflection, in order to reduce the deflection of wide cut printing paper 2 ', will use various data, the transporting velocity of two feed roller 5a, 5b that calculating conveying wide cut printing paper 2 ' is correlated with should become the speed (step S111) of several cm/s respectively between several seconds.In other words, in above-mentioned example, to diminish or become zero in order to make, as long as how calculating changes the transporting velocity of 2 feed roller 5a, 5b according to the wide cut printing paper 2 ' oscillating quantity (apart from x) and the deflection one angle θ of the wide cut printing paper 2 ' that calculates of the oscillating quantity (distance y) when returning and throughput direction when moving.
According to this result of calculation, controller 20 is connected the motor speed of motor 22a, 22b by appropriate change and feed roller 5a, 5b, makes the rotation speed change of feed roller 5a, 5b.Like this, just can change feed roller 5a, 5b carrying capacity, the deflection of wide cut printing paper 2 ' is diminished wide cut printing paper 2 '.
Then, after travelling carriage 12 moves to position of rest once more, temporarily stop to move at that moment travelling carriage 12.At this moment with travelling carriage 12 be in an opposite side with position of rest turn around the same during the position, wide cut printing paper 2 ' be transferred again fixed paper feeding amount.The conveying of appropriate change 2 feed roller 5a, 5b control makes the deflection of wide cut printing paper 2 ' become zero (reducing) but at this moment.Therefore, wide cut printing paper 2 ' as shown in figure 13, deflection hardly, the right end position almost consistent (step S112) of the right end position of wide cut printing paper 2 ' and correct printing paper transport path.
Specifically, for printable zone, when wide cut printing paper 2 ' was the deflected condition that left side shoulder alarmmed, the transporting velocity of change feed roller 5b made it in the transporting velocity of desired time internal ratio feed roller 5a greatly.Otherwise for printable zone, when wide cut printing paper 2 ' was the deflected condition that right shoulder alarmmed, the transporting velocity of change feed roller 5a made it in the transporting velocity of desired time internal ratio feed roller 5b greatly.
In addition, when travelling carriage 12 was in position of rest, the conveying of appropriate change 2 feed roller 5a, 5b was controlled, and just can improve the swing state of wide cut printing paper 2 '.But may not leave no choice but as mentioned above, only the conveying that feed roller 5a, 5b are carried out is once controlled, just eliminate the deflection (deflection that makes wide cut printing paper 2 ' be zero) of wide cut printing paper 2 ', make the right end position basically identical of its right end position and correct printing transport path.In other words, both can once carry control, the deflection of wide cut printing paper 2 ' is diminished feed roller 5a, 5b; Also can carry out repeatedly conveying control, eliminate the deflection of wide cut printing paper 2 ', make the right end position basically identical of its right end position and correct printing transport path feed roller 5a, 5b.
Like this, when travelling carriage 12 is in position of rest, wide cut printing paper 2 ' decide paper feeding amount conveying (comprising the deflection correction) finish after, travelling carriage 12 begins to carry out repeatedly and above-mentioned the same action toward moving once more.
On the other hand, conclude that wide cut printing paper 2 ' is not during deflection, owing to do not need wide cut printing paper 2 ' is carried out the deflection correction, so with travelling carriage 12 be in an opposite side with position of rest turn around the same during the position, do not carry out deflection correction ground with wide cut printing paper 2 ' carry fixed paper feeding amount (step S113).Travelling carriage 12 begins to carry out repeatedly and above-mentioned the same action toward moving more then.
Like this, travelling carriage 12 every round trips according to the oscillating quantity of the wide cut printing paper that calculates when the round trip 2 ' when moving and the oscillating quantity when returning, improve the deflection of wide cut printing paper 2 '.Therefore, wide cut printing paper 2 ' is being revised, after making it the right end position basically identical of the correct transport path of not deflection, right end position and printing paper, in the printing afterwards, even deflection appears in wide cut printing paper 2 ' once more, also can prevent to continue to keep the deflection of wide cut printing paper 2 ', or make this deflection further carry printing with increasing.
In addition, here explanation is, to wide cut printing paper 2 ' not dislocation on the width of correct transport path, and when deflection appears in throughput direction, change 2 feed roller 5a, 5b and carry control, to reduce the situation of wide cut printing paper 2 ' and the deflection of throughput direction.But wide cut printing paper 2 ' does not have deflection on its throughput direction, and when dislocation on the width of correct transport path, occurring, and both there had been deflection in wide cut printing paper 2 ' on throughput direction, when on the width of correct transport path, dislocation occurring again, can revise too.
Therefore, wide cut printing paper 2 ' does not have deflection on its throughput direction, and when dislocation on the width of correct transport path, occurring, change 2 feed roller 5a, the conveying control of 5b, to reduce the dislocation of wide cut printing paper 2 ' on the width of correct transport path, promptly work as wide cut printing paper 2 ' and on its throughput direction, do not have deflection, but when the right end position of wide cut printing paper 2 ' misplaces to the left than the right end position of correct printing paper transport path, at first in desired time (time T 1), make the transporting velocity of feed roller 5a bigger than the transporting velocity of feed roller 5b, then, in desired time (time T 2), make the transporting velocity of feed roller 5b bigger than the transporting velocity of feed roller 5a.Otherwise, for printable zone, when wide cut printing paper 2 ' does not have deflection, when the right end position of wide cut printing paper 2 ' misplaces to the right than the right end position of correct printing paper transport path, at first, in desired time (time T 3), make the transporting velocity of feed roller 5b bigger than the transporting velocity of feed roller 5a, in desired time (time T 4), make the transporting velocity of feed roller 5a bigger then than the transporting velocity of feed roller 5b.
In addition, when both there had been deflection in wide cut printing paper 2 ' on throughput direction, when on the width of correct transport path, dislocation occurring again, also the same with said method, change the conveying control of 2 feed roller 5a, 5b, the deflection of wide cut printing paper 2 ' on throughput direction reduced, and the dislocation of wide cut printing paper 2 ' on the width of correct transport path reduced.
In addition, in the present embodiment, correctly do not packed in the housing 30, when wide cut printing paper 2 ' is carried with the state that is inclined to throughput direction even hold the paper storehouse of the coiling portion of wide cut printing paper 2 ', also, can improve the swing state of wide cut printing paper 2 ' with above-mentioned the same.
In addition, in the ink-jet printer 1 of present embodiment, when travelling carriage 12 back and forth movements, whole device rock the swing that causes wide cut printing paper 2 ' sometimes.Even but in this case, also can improve the swing state of wide cut printing paper 2 ' with above-mentioned the same.
In sum, after adopting the ink-jet printer 1 of present embodiment, can monitor the angle excursion of wide cut printing paper 2 ' and throughput direction by printing paper sensor 38, control the rotating speed of 2 feed roller 5a, 5b respectively, so that in the print area relative, the angle excursion of wide cut printing paper 2 ' is diminished with printhead 11.Therefore, when going up print image toward the wide cut printing paper of being carried by 2 feed roller 5a, 5b 2 ', the angle excursion that can suppress wide cut printing paper 2 ' becomes the image quality that causes after big and descends, perhaps with the problem of the state print image that favours the wide cut printing paper.In addition, for printable zone,,, enlarge the zone of drawing a picture so can reduce spill-over owing to can carry wide cut printing paper 2 ' with the very little state of angle excursion.
In addition, when using ink-jet printer 1 not stay the limit to print,, stain so can suppress lettering platen 13 because ink receiving portion 14a～14d can not departed from the end of the width of wide cut printing paper 2 '.
In addition, with printhead 11 print images the time, wide cut printing paper 2 ' is in halted state, so can more effectively suppress degradation problem under the image quality.
In addition, because printing paper sensor 38 is point sensors, being installed in can be on the travelling carriage perpendicular to the direction back and forth movement of the throughput direction of wide cut printing paper 2 ', so as the swing state test section, can not use the large-scale plant of line sensor and so on, and use small-sized device, thereby can reduce the manufacturing cost of ink-jet printer 1.
In addition, because the structure that ink-jet printer 1 adopts is by being installed in the deflection of a printing paper sensor 38 detection wide cut printing papers 2 ' throughput direction on the travelling carriage 12, so can more effectively reduce the cost of swing state test section.
In addition, because when the long paper wide cut printing paper 2 ' print image that coiling portion in the paper storehouse is launched, the deflection of wide cut printing paper 2 ' is not carried with increasing, so can on long paper wide cut printing paper 2 ', write down high quality image from the beginning to the end.
